Hi - experienced programmer but this is my first Python program.
This URL will retrieve an excel spreadsheet containing (that day's)
msci stock index returns. http://www.mscibarra.com/webapp/inde...EIPerfRegional
Want to write python to download and save the file.
So far I've arrived at this:

xlApp = Dispatch("Excel .Application")
# test 1
# xlApp.Workbooks .Add()
# xlApp.ActiveShe et.Cells(1,1).V alue = 'A'
# xlApp.ActiveWor kbook.ActiveShe et.Cells(2,1).V alue = 'B'
# xlBook = xlApp.ActiveWor kbook
# xlBook.SaveAs(F ilename='C:\\te st.xls')
# pdb.set_trace()
response = urllib2.urlopen ('http://www.mscibarra.c om/webapp/indexperf/

Woops hit Send when I wanted Preview. Looks like the html [quote] tag
doesn't work from groups.google.c om (nice).
Anway, in test 1 above, I determined how to instantiate an excel
object; put some stuff in it; then save to disk.
So, in theory, I'm retrieving my excel spreadsheet with
response = urllib2.urlopen ()
Except what then do I do with this?
Well for one read some of the urllib2 documentation and found the
Request class with the method has_data() on it. It returns False.
Hmm that's not encouraging.
I supposed the trick to understand what urllib2.urlopen is returning
to me; rummage around in there; and hopefully find my excel file.
I use pdb to debug. This is interesting:
(Pdb) dir(response)
['__doc__', '__init__', '__iter__', '__module__', '__repr__', 'close',
'code', '
fileno', 'fp', 'geturl', 'headers', 'info', 'msg', 'next', 'read',
'readline', '
readlines', 'url']
(Pdb)
I suppose the members with __*_ are methods; and the names without the
underbars are attributes (variables) (?).
Or maybe this isn't at all the right direction to take (maybe there
are much better modules to do this stuff). Would be happy to learn if
that's the case (and if that gets the job done for me).

The docs ( http://docs.python.org/lib/module-urllib2.html) are pretty
clear on this:
"""
This function returns a file-like object with two additional methods:
"""
And then for file-like objects: http://docs.python.org/lib/bltin-file-objects.html
"""
read( [size])
Read at most size bytes from the file (less if the read hits EOF
before obtaining size bytes). If the size argument is negative or
omitted, read all data until EOF is reached. The bytes are returned as a
string object. An empty string is returned when EOF is encountered
immediately. (For certain files, like ttys, it makes sense to continue
reading after an EOF is hit.) Note that this method may call the
underlying C function fread() more than once in an effort to acquire as
close to size bytes as possible. Also note that when in non-blocking
mode, less data than what was requested may be returned, even if no size
parameter was given.

You don't need to convince Python, just write it to a file.

Nope - must have been stumbling over my own feet.
'wb' _is_ necessary (as I would expect).
So it works:
# pdb.set_trace()
response = urllib2.urlopen ('http://www.mscibarra.c om/webapp/indexperf/

# print(response)
f = open("c:\\msci. xls",'wb')
f.write(respons e)
f.flush
f.close
I know the f.flush and f.close are redundant - in the sense that both
flush the contents to disk. So I can probably just take out the
f.flush.
Thanx for the help.
